EPIC contract awarded to CSO/ABB consortiumContracts, Tenders and Rates // August 11, 2000
The work, which was originally tendered as two separate contracts, will be performed by the two companies working together in a consortium.
The 'base case' scope of work for Nuggets Phase 1 comprises a new manifold at Nuggets tied back by a 40km 12in pipeline with a 3in MEG piggyback, to the North Alwyn Platform.Two subsea wells will be installed, one adjacent to the manifold and one 3km away, connected by a 6in and 2in pipeline. Controls are provided from the Dunbar platform via a 20km umbilical to the manifold and onwards to the two wells. First gas is scheduled for mid-October 2001.
The contract included two options for additional facilities, which have just been awarded as well to the consortium. Nuggets Phase 3 comprises a second manifold with an adjacent well, umbilical and a 14.5km 12in pipeline with a 4in MEG piggyback line tied back to the Phase 1 manifold.The Nuggets phase 2 option included a further well tied back 4.4km to the Phase 3 manifold by a 6in pipeline with a 2in MEG piggyback line and umbilical.
CSOL will design, procure and fabricate the pipeline systems and perform the offshore installation and tie-in of the pipelines, umbilicals and manifolds.
Installation of the system will be undertaken, starting summer 2001, by the CSO Group fleet of vessels, in particular the reelship CSO Apache and the newly converted CSO Constructor, with trenching support from the Normand Pioneer (completed with multi-pass plough spread). Additional support will be provided by CSO dive support vessels.
Dave Cassie, Managing Director of Coflexip Stena Offshore Ltd., stated: "CSOL is delighted to have the opportunity to work again with TotalFinaElf. The Nuggets project enables CSO to demonstrate its wide ranging technical capability and, in consortium with ABB, to provide our client with an integrated solution."
Within the contract, ABB will provide horizontal subsea trees, the controls system, the umbilicals supplied by Duco and manifolds.
The control system and umbilical installed in the initial phase will have capacity to support the full field development, including expansions, resulting in an overall subsea step-out of 43km. ABB will supply their COPS (communications on power) controlsystem that is field proven beyond this distance.
Peter Hewlett, Managing Director of ABB Offshore Systems in the UK said: "This is a breakthrough for ABB on the UK Continental Shelf and we are pleased that TotalFinaElf selected ABB and Coflexip Stena Offshore for this project".
